Thick Film Flat Plate Solar Water Heater
Using metal resistance paste as the main raw material, printing to form a pure resistance layer circuit, which can have a stable power after being energized. With this characteristic,the resistor integrated circuit (referred to as a circuit) is formed. The sudden change in temperature caused by the increase in resistance can be adjusted from room temperature to hundreds of degrees. The R-T curve is linear. This characteristic is called the resistance effect of the positive temperature coefficient circuit.
It not only has the general characteristics of thermistor, but also because of the uniqueness of its material composition and process, it also has unique and excellent performance that the general thermistor does not have, so that the control accuracy and sensitivity can be greatly improved. It can realize multi-temperature zone gradient setting and intelligent control.
Seven Advantages:
●1. The efficiency is as high as 97%
●2. When applied to water or fluid , the substrate is not easy to scale
●3. The power density is generally produced as 60W/cm2, which is several times that of traditional ones
●4. It is uniform and stable. In the case of electric control, the temperature fluctuation is small, and the temperature control accuracy is ±2℃
●5. Wide application range, AC/DC universal, and it can be made into different shapes according to different design requirements
●6. Compared with the traditional ones, it has a small tcapacity, so the speed is extremely fast, and there is very little residual heat after power failure
●7. The water and electricity separation is formed through the inorganic oxide insulating layer, which has the characteristics of anti-oxidation, the power attenuation is almost 0, and the service life can reach 15000h
